APS_ACTIVITY_RESUMEREQ_
This procedure allows you to request the resumption of an activity that had previously
been interrupted. The activity could previously have been in use on this connection or
on another connection.
You can issue an activity resume request only if no activity is in progress and you hold
the major/activity token. You must also hold the data token and the synchronize-
minor token, if they are available on the connection.
This procedure also allows you, optionally, to use basic concatenation to send a token
give request primitive along with the activity resume request primitive.

status returned value
INT
indicates the outcome of the call. For the possible values of ZAPS-VAL-STATUS-
xxx, see “Status Codes” in Appendix B.
cepi input
INT:value
is the connection endpoint identifier (CEPI) for this connection.
activity-id input
INT .EXT:ref:(ZAPS-DDL-ACTIVITY-ID)
is the new identifier for this activity.
old-activity-id input
INT .EXT:ref:(ZAPS-DDL-ACTIVITY-ID)
is the identifier that the activity had when it was last interrupted.
sync input
INT(32):value
specifies a new synchronization point value in the range 0 through 999998. See
ZAPS-DDL-SYNC in Appendix A for further information about this parameter.
